Title
(EN) COMPOSITE NANOARCHITECTURE UNIT, MULTILAYER COMPOSITE, AND METHOD FOR MANUFACTURING COMPOSITE NANOARCHITECTURE UNIT
(FR) UNITÉ À NANOARCHITECTURE COMPOSITE, COMPOSITE MULTICOUCHE ET PROCÉDÉ DE FABRICATION D'UNE UNITÉ À NANOARCHITECTURE COMPOSITE
Abstract
(EN) A composite nanoarchitecture unit is disclosed. the unit comprises a columnar film grown on top of another layer where the columns touch each other at the top forming arches having optimized characteristics. This nanoarchitecture unit, called nano-vault, achieves high mechanical stability for films under strong and variable stress action.
(FR) Une unité à nanoarchitecture composite est divulguée. L'unité comprend un film colonnaire développé au-dessus d'une autre couche où les colonnes se touchent au niveau de leur partie supérieure, formant des arches présentant des caractéristiques optimisées. Cette unité à nanoarchitecture, appelée nano-voûte, permet d'obtenir une stabilité mécanique élevée pour des films soumis à un effet de contrainte puissant et variable.
